1 Claim.

The present invention has referencegenerally to improvements in vehicle wheelsand more particularly pertains to a wheel of the type described in my Patent No. 1,988,352. I 5 It has been found that on high speed ,cars the tire disclosed in the above" mentioned patent should be used without the inner tread member, and an easy way should be found to improve the changing operation of a punctured tire. Therefore, the present invention relates to an improved wheel which enables the tire to be attached easily, and used on high speed cars without the inner tread member.

Other objects as well as the nature, characteristic features and scope of the invention will be more readily apparent from the following description taken in connection 'with the accompanying drawing and pointed out in the claim.

The invention is clearly illustrated in the atc'ompanying drawing, in which:

Fig. l is a side elevational view of the improved devicepartly broken away to illustrate a portion of the wheel and tire in circumferential section;

Fig. 2 is a transverse sectional view through a complete wheel particularly showing the construction of the improved tire;

Fig. 3 shows a new type of lifting wedge, to be used in case a tire or wheel should be quickly so replaced.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring to the accompanying drawing and particularly. to Fig. 2 there is provided a metal disc-like member 20 having a lateral arcuate extension I which forms an auxiliary rim for the wheel. The disc-like ember 20 is reinforced by means of a diaphragm 2 which is secured to- 40 the hub portion of the disc-like member by means of bolts 3. The auxiliary rim I and the peripheral edge of the diaphragm 2 are welded together and they represent the fixed part of the wheel. The'metallic auxiliary rim I .on

which the tire can be placed, is shaped as shown in Fig. 2 and the metallic ring piece I4 or the rim portion ll of the tire itself 'flts the arcuate shape of the auxiliary rim I and: the inner edgeof the rim portion ll rests on the shoulder l. I

Inward mogement of the detachable tire is limited by the flat surface of the disc-like inember 20 adjacent the shoulder 4. Through the' annular flat surface adjacent to shoulder 4 pass the specially designed coupling pins 5, their 5; head being welded to the part I.

able to replace a punctured tire.

The part I is'shaped so as to provide an annular grooved ringholder I to receive a rubber ring 6 which is adapted to protect the-metalparts of the wheel by carrying the weight of the vehicleover roughpavement inicase the tire 5 tube has been punctured or deflated. The ringholde'r I is'also useful to avoid any accident which may be caused by a loss of control of the machine if a tire hasbeen punctured at high speed. In this case, the car wheel radius is reduced only 2 or 3 inches and the direction control can easily be maintained. It also permits the car to be moved at a moderate speed,-leaning on this auxiliary tire 6, and finally, the ringholder ,I-is useful to lift the'car in case of a de- -iiated tire, by means of a single wedg'e piece .rubber ring 6 can run along the inclination of the upper surface and lift the car enough to be 20 Once .the car wheel on which the tire has to be replaced, reaches the horizontal wedge surface. the car must be braked. The changing procedure of the tire. itself, after taking off the wheel cover, 95 consists only in .pressing with both hands the ends of the steel ring I3 1), which fits in corresponding grooves provided at the inner side of each coupling pin 5 By the application of such pressure, the diameter of the steel 30 ring I3 is made smaller, and it can be disengaged from the pins 5. After such operation, the deflated tire can bereplaced by a new one. The tire is constituted by two metal rim portions I2 and IA. The rim portion I4 is arranged 3 with its outer surface against the rim I. As shown in Fig. 2, the peripheral portions of the rims I2 and l'l are inwardly curved in opposite directions to provide circumferential seats for the marginal portions of the tread member 9. 40

As already known, the marginal portions II are usually reinforced by steelstrips or .wire and this enables a better fastening of the tread2 member inside the rim portions I2 and I4. The air pressure of the inner tube III also helps to 45 secure thetread member between the rim portions I2 and I4. r

Having thus fully described the invention, what is claimed as new and desired to-be secured by Letters Patent is: a N In a vehicle wheel, a disc-like hub member having an integral annular arcuate shaped lateral-peripheral extension providing an auxiliary rim portion for. the wheel, an annular shoulder formed on the disc-like member by an cm part 01' the disc-like member, a rigid arcuate portion having an integral inwardly projecting shaped annular rim portion shaped to flt within time with the inner edge thereof resting on said auxiliary rlm portion, said rim portion havsaid shoulder, and means for detachably securing an integral inwardly directed flange with ing said rim portions to the disc-like member. the inner edge thereof resting on said shoulder,

' a 5 another rigid. oppositely curved annular rim LUIS GALIiNDO.
